Dr. Jennifer C. Schultens, AWM Representative, Co-Chair JCW

Jennifer Schultens was born in 1965 in West Germany to American parents. She attended the Freie Waldorfschule Kassel where she earned her Abitur in 1984. She moved to the USA to study mathematics and Russian at Bryn Mawr College where she graduated magna cum laude in 1988. She earned her Ph.D. at UCSB under the direction of Martin Scharlemann with a dissertation entitled “The classification of Heegaard splittings for some Seifert manifolds” in 1993. She taught at Emory University from 1993 to 2003, earning tenure in 1999. She took a leave from Emory to pursue an NSF postdoc under the direction of Andrew Casson and Rob Kirby at UC Berkeley from 1995 to 1997. She married mathematician Misha Kapovich in 2002 and moved to UC Davis in 2003. Schultens’ work delves into the nuts and bolts of 3-manifolds, especially surfaces of two notable varieties: Incompressible surfaces, which are more or less those whose fundamental group injects into that of the 3-manifold and Heegaard surfaces, which bound handlebodies (3-dimensional fattenings of graphs) on either side. With regard to incompressible surfaces, she envisions an analog of the curve complex promoted up one dimension to encode surfaces in a 3-manifold. With regard to Heegaard surfaces, she tries to understand the relation between distinct Heegaard surfaces in a given 3-manifold and also the totality of such surfaces as encoded in the width complex.  She is the author of several research articles on the subject along with two books: Introduction to 3-manifolds and, joint with Saito and Scharlemann, Lectures on generalized Heegaard splittings.
